Monitoring a Channel
When no signals are present, the squelch on the transceiver automatically mutes the speaker so you will not hear background noise. Using the MON key, you can open the squelch to unmute the speaker. This allows you to:
•confirm the channel activity so you don’t make a call while another party is using the same channel
•adjust the volume level without having to wait for a call
•listen to an intermittent call (due to a weak signal) without it continuously cutting out
To manually open the squelch, press and hold the MON key.
•When squelch is open, the 
icon appears on the display and the LED lights green.
To return to normal operation, release the MON key.
